Typha is a monocotyledonous plant with perennial defoliation and perennial water. Also known as Pucao, Pucai, and Timothy. Because the spikes are candle-shaped, they are also called water candles. The stem is extremely short and not obvious.

A warm, well-lit environment, born in ponds, river beaches, canals, wet and watery places. Typha is one of the important aquatic economic plants.
